Can you put music from your iPod to iTunes then put the music in your iPhone?

My friend had put some music on my iPod nano a few years ago and I want it on my iPhone. I have a PC with I iTunes but don't know how to transfer it.

Did he buy the music from iTunes? It should automatically show when you buy it from iTunes.

It's easy for you to do this. You just need iPhone transfer software to transfer music of iPod to iPhone directly.

Unlike the iPod touch, many nanos can be "browsed" or explored using "windows explorer". You are looking for the "control folder". Try googling that. Once you've found the files you can copy them to your HD and import them into Itunes. Then put them on your iPhone as you would any music on your HD.
